On one out of 4 Windows 10 PCs NS went crazy and started removing numerous files (mostly old items, but a few currently used programs too) declaring them to be infected with the Heur.AdvML.C Heuristic virus. I ran a scan on another PC of one of the exe files it removed and NS said the file was fine.
I had just used the Remove and Reinstall program yesterday because NS was acting "weird" (running all the time).
I'm currently on hold on the phone waiting for tech support.
